Skeptoid is a weekly science podcast dedicated to furthering knowledge by blasting away the widespread pseudosciences that infect popular culture, and replacing them with way cooler reality.

Each weekly episode focuses on a single phenomenon — an urban legend, a paranormal claim, alternative therapy, or something just plain stupid — that you've heard of, and that you probably believe in. Skeptoid attempts to expose the folly of belief in non-evidence based phenomena, and more importantly, explains the factual scientific reality.

From the sublime to the startling, no topic is sacred, politically incorrect though that may be. 175,000 weekly downloads.Read what people are saying.
